Andrew N. Christensen was a long time resident of the Livermore Valley and served on the Board of Trustees of the Green School District for 19 years and was a member of the Board of Trustees of the Livermore Joint Union High School District for 14 years. In addition to his community and civic participation, Mr. Christensen was also a cattle and horse rancher.

On June 29, 1966, the Board of Trustees of the Green Joint School District of Alameda and Contra Costa Counties passed a resolution to rename the Greenville-North Site #1 school site Andrew N. Christensen School.

Andrew N. Christensen School was established as a K-5 elementary school in 1977. The first sixth grade class was added in 1990. The remodeling of existing buildings and the addition of new classrooms was completed in 1991. Over the next several years, Christensen transitioned to its present configuration serving grades six through eight and became Andrew N. Christensen Middle School. We are able to accommodate more than 900 students, a capacity we haven’t reached. We are proud to have 42 spacious classrooms arranged in grade level or subject matter “clusters”. At the center of each cluster is a mini-courtyard, complete with benches and greenery, where students study, snack, and socialize when class is not in session. Our campus includes four science labs, two home economic teaching kitchens, a library, an administration office, a gymnasium with locker rooms, two music rooms, two computer labs, a multipurpose room, a kitchen, a strength training room, an outdoor eating area and a courtyard.
